INVALIDS CHAIR.

Specification of Letters Patent.

Patented Nov. 27, 1911*?.

To all 'whom it may concern.'

Be it known that we, MARY L. HENNING and CLARA R. WOEBER, citizens of the United States, and residents of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Invalids Chairs, of which the following is a specification.

This invention relates to a chair or seat for infants or invalids and more particularly to a chair arranged to facilitate theV operation or exercise of certain of the functions of the body and it has for its object generally to provide a chair of this type adapted to minimize the inconvenience both to the infant or invalid andto the mother or nurse, or other attendant in charge.

A further object is to provide a chair 0f this type which will be hygienic in every respect, a still further object being to provide a collapsible or foldable chair of this type characterized by simplicity of construction.

For further comprehension of the invention and of its objects and advantages reference will be had to the Jfollowing description and accompanying drawings, the various novel features of the invention being more particularly defined in the appended claims. i

Figure 1 of the drawings is a perspective view of a chair embodying the invention.

Fig.y 2 is a side view of the chair in folded or collapsed position.

Fig. 3 is a plan view of one side thereof, both sides being of similar construction.

Fig. 4 is an enlarged detail vertical section taken longitudinally through the center of the chair.

Fig. 5 is a vertical section on the line 5-5 of Fig. 3.

In the embodiment of the invention here Y illustrated, the chair comprises a pair of side frame bars 2 extending horizontally along each side of the seat portion ofthe chair. Depending from the front end of these bars are the front legs 4 and depending from the rear ends of these bars are the rear legs 6. The front legs are hinged as at Sto the side frame bars 2 to permit of their being swung rearwardly and upwardly into the folded position adjacent the side frame bars, as indicated in Fig. 2, while the rear legs 6 are likewise hinged at 11 to the rear ends of the side frame bars to permit of their being` swung forwardly and upwardly into the folded position adjacent the side frame bars. The front legs may be rigidly connected together by the cross bar 13 while a similar cross bar 15 may connect the rear legs to one another.

The front and rear legs are` held in eX- tended position by the jointed straps, 16 and 17, respectively, each hinged at one end to the side frame `bars 2 and at their other ends to the front and rear legs 4 and 6,'respectively, the straps 16 and 17 being so arranged that the front and rear legs ineline downwardly and outwardly toward the front and rear. Any well known means may be provided to hold the straps in extended position. The front ends of the side frame bars are rigidly connected by a cross bar 18 having the transversely spaced depressions 19 therein.

Hinged to upturned lugs 20 formed on the rear ends of the side frame bars 2 are a pair of arms 21-22 forming the side frames for the back of the chair. l prefer to make these arms in two sections with the upper portions 21 telescoping into the lower portions 22 to make the chair more compact when collapsed, any suitable means, such as the set screws 23, being employed to retain the upper portions 21 in the desired position. These upper portions 21 are united by a rigid crosspiece 24 at the upper end thereof.

The chair back may be adjustably held in different inclined positions by suitable means, as the bail 26 hinged to the arms 22 and engaging in notches 27 in the rear legs 6.

Hinged to the front ends of the side frame bars on the before mentioned pivots 8 are a pair of arms 30 forming a frame for a foot rest extension connected at their front ends by a. `rigid cross bar 31. Suitable means, as the bail 32, hinged to the arms 30 and engaging in notches 33 in the front legs 4, may be provided for adjustment of the foot rest extension.

The back, seat and foot rest extension :may

be formed of a continuous strip of canvas or other suitable material connected at one end to the cross piece 24 and at its opposite end 4'to the cross piece 31, and resting upon the cross bar 18. Y

Formed in that portion of the canvas constituting the seat of the chair is an aperture 40, while a pan 41 is adapted to be supported beneath such aperture. a pair of supporting strips 42 and 43 are hinged, as at 44 and 45, lto the side frame bars 2 and are adapted to 'support the pan, as clearly shown in Fig. 4, these strips being held in proper position by extensions 46 and 47 thereon which enga-ge the stop members 48 and 49 on the side frame bars 2. Studs 50 and 51 may be provided on the supporting strips 42 and 43 to position the pan thereon, allowing the same to be freely inserted or withdrawn vfrom one side, as will be apparent,

We prefer to provide also the side arms here shown as each comprising a horizontal member 60, mounted on the upper ends of parallel links 62 and 63, and an inclined member 61, mounted on the face ends of the parallel links 64 and 65. The arms 62 are hinged at their 'lower ends to upturned lugs Y 69 on the ends of the cross b ar 18, the links 65 being hinged to the side arms 21 as shown while the links 63 and 64 are hinged on the lugs 20. Set screws 66 may be employed to hold the parallel links in any adjusted position. The spaces inclosed by these side arms may if desired be filled with cloth or canvas suitably attached to the arms.

, AThe chair can be made in different sizes to accommodate either infants or adults.

The manner lin which the chair is folded will be readily understood from Fig. 2, The front legs being hinged on the inside of the side frame bars 2 and the rear legs on the outside, as clearly shown in Figs. 1 and 3, these legs do not interfere with one another when folded inwardly, while the straps 16 and 17 buckle linwardly in a well known manner. The lstrips 42 and 43 for supporting the pan swing upwardly alongside the bars 2 and are thus out of the way of vthe legs. `The foot -rest extension 'is Vfolded back over the bottom of the seat and the back folded forward over Ythe top of the seat the upper arm kmembers21 being telescoped into the lower arm members 22. The side arm members 60and 61 `are swung `on the links 62,163, 64 and 65 by 'loosening the screws 66 and folded' conveniently adjacent the side frame vbars 2 and arms 22.

The adjustment of the canvas 35 by means of the telescoping arms 21 and l22, by which the portion of the canvas forming the .chairy l 'back is 'adjusted longitudinally of itself, also permits of Ladjustment or regulation of the sag of the'canvas,y 'as may 'be desired for Vtheir hinges. As here shown, n

comfort or convenience, or to raise or lower the aperturedV seat portion with relation to the pan. The seat and back may be made of an integral member of non-flexible material, such ask aluminum, in which case Vthe telescoping arms 21, 22, permit of adjustment of the seat byV swinging the arms on The object of the space depressions 19 is to cause a slight separation of the legs of the infant when seated kin the chair.

The utility and advantages of this improved chair will be obvious to those familiar with the care of infants or helpless people generally from the foregoing description. z

VIt will be apparent that variousxchanges and modifications might be made inthe construction as herein described without departing from the spirit of the invention and the right is therefore reserved to all such changes and modifications `as come within the scope of the appended claims. l

What we claim is i 1.v A chair ofthe type describedcomprising a seat and back, means for supporting a pan under the seat, means for adjusting the said back longitudinally of itself the said back and ,seat being connected to one another to cause longitudinal adjustment of the back to effect. vertical adjustment of the seat.V
